DIMMs
The system board contains four DIMM sockets labeled 1 through 4 (Figure 4-9).
Each socket can hold a single 72-bit DIMM module with 64MB, 128MB,
256MB, 512MB, or 1GB of memory. When all four sockets are populated, the
system board supports a maximum of 4 GB of memory with 1GB DIMMs. A
DIMM will always be installed in socket 1. When you install additional
DIMMs, you must start with the first empty socket next to the DIMMs already
installed. When you remove DIMMs, you must start with the highest number
occupied DIMM socket on the system board.
